Know what risks to avoid and overcome to maximize these platforms for your organization. Introduction to pattern matching in Java Pattern matching in Java helps developers better describe data structures and avoid runtime errors, while making code more
The Ecllipse Virgo Web Server from EclipseRT is a completely module-based Java application server that is designed to run enterprise Java applications and Spring-powered applications with a high degree of flexibility and reliability. It offers a simple yet comprehensive platform to develop, deploy, and service enterprise Java applications. The Virgo kernel supports the core concepts of Virgo and i
There have been bubbles of interest about OSGi in the Java community over recent years. I for one was very excited about the advent of a modular Java platform that freed us from the classloader issues in the JDK manifested best by Jakarta commons-logging (clogging our app servers). OSGi was going to change everything, dependencies would be completely isolated (no more tripping over conflicting de
今回のテーマは「クラウド」という事でしたが、空気を読まずに熊沢先生の「Modularityを考える - 複雑系のアーキテクチャ」への自分の考えを発表してきました。多分に電波を含んでいたので、質問されるとしどろもどろになっていましたが、今回伝えたかった「モジュール化(Modularity)はオブジェクト指向から抽象化を一歩すすめたもの」と言うあたりには納得していただけたようです。 で、結局のところ日本のSIerがやっている業務システムへモジュール化はどうやってやっていくのがいいか、という事に対してうまく答えられなかったわけで、くやしいのでブログに書こう。 モジュールは必要か 自分はシステムが小さいうちからモジュールを意識して作っておく事は保守の面でいいと思ってます。DIの普及により、インターフェースに対してプログラミングを行う作法で実装が行われるようになりました。モジュールを意識して実装を行
Motivation The goal of the Apache Felix OSGi Bundle Repository (OBR) is two-fold: To simplify deploying and using available bundles with Felix. To encourage independent bundle development so that communities of interest can grow. OBR achieves the first goal by providing a service that can automatically install a bundle, with its deployment dependencies, from a bundle repository. This makes it easi
News A new tool for generating bundle manifest headers, called mangen, is now available. (June 10, 2005) Updated HTTP Service bundle to correct a minor problem with re-registering aliases. (April 6, 2005) Added a new donated HTTP-based administration bundle, called HTTP Shell. This bundle supports shell and OBR access and provides support for basic user authentication.

If you build an application for the SpringSource dm Server, or any other OSGi platform, you'll probably encounter the uses directive before long. Unless you have a clear understanding of the purpose of the directive, you won't know when to code it and you'll be left guessing when a bundle fails to resolve because of a uses conflict. This article should give you a thorough understanding of the uses
